Hydrogen and oxygen combine in the ratio of 1 : 8 by mass to form water. What mass of oxygen gas would be required to react completely with 3 g of hydrogen gas?
Answers
Answer:
The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass. It implies that any pure sample of a compound, no matter the source, will always consist of the same elements that are present in the same ratio by mass.
Example: Pure water will always contain hydrogen and oxygen in a fixed mass ratio. Gram of water consists of approximately 0.11 grams of hydrogen and 0.88 grams of oxygen and the ratio is 1:8
For every 1g of hydrogen = 8g of oxygen.
Therefore, for 3g of hydrogen, the quantity of oxygen = 3 x 8 = 24g
Hence, 24g of oxygen would be required for the complete reaction with 3g of hydrogen gas.
plz mark as the brainliest :)
Answer:
The answers is 24 g
Explanation:
Hence, 24 g of oxygen would be required for the complete reaction with 3 g of hydrogen gas.
